Non-parametric 3D surface completion

Abstract

We consider the completion of the hidden or missing portions of 3D objects after the visible portions have been acquired with 2 1/2 D (or 3D) range capture. Our approach uses a combination of global surface fitting, to derive the underlying geometric surface completion, together with an extension, from 2D to 3D, of nonparametric texture synthesis in order to complete localised surface texture relief and structure. Through this combination and adaptation of existing completion techniques we are able to achieve realistic, plausible completion of 2 1/2 D range captures.
